- Patch panels may be connected in a variety of ways, and the above configurations are just two such examples. Depending on an amount of customers to support, additional patch panels may also be included.
- Each patch panel port of the present application is provided with contacts that enable the patch panels to identify when patch cord plugs have been inserted into ports of the patch panel. Further, each patch panel port is provided with indicator lights (or other signaling mechanisms) that allow the patch panels to guide steps of the addition or removal of patch cords connected between patch panels.

- the patch panel system of the present application is an Intelligent Physical Layer Management (IPLM) tool including modular, intelligence-ready patch panels, PMMs, enhanced patch cords, and software that enables operations and management functions of the system to be performed more easily.
- IPLM Intelligent Physical Layer Management
- aspects of the present application enable a technician to perform patching between patch panels more efficiently. A sequence of steps is provided below to create a connection between a patch panel and a switch using the patch panel system of the present application.
- FIG. 12B is an example block diagram illustrating an interconnect architecture, which is a configuration including the switch 1202 coupled to the end computer 1208 through one panel 1204 .
- Each of the switch 1202 and the patch panel 1204 communicate through network management software 1210 .
- the panels 1204 are also provided with “intelligence” in the form of circuitry.
- the ninth wire of the nine-wire patch cord will make an electrical connect with the contacts on the wing board, as shown at block 1302 .
- the wing board electronics can determine both the type of cable (nine-wire patch cord or ten-wire patch cord), and whether the cord is plugged into a patch panel at the other end (far end), as shown at block 1304 .
- the wing boards will initiate communications and exchange data via the ninth wire, as shown at block 1306 .
- the technician makes the connections as desired between patch panels with the nine-wire patch cord, and once the connections are completed, the wing boards send connection information to the PMM, which forwards the information to the NMS for display and storage.
- Similar steps are performed to create a connection within an interconnect system architecture between a patch panel and an Ethernet switch or Ethernet router.
- a sequence of steps can be completed that are referred to as I-Cord provisioning.
- the PMM that is inserted into the patch panel will act as the intelligence to learn from a patch cord both the cord's unique ID and connection status, and will subsequently instruct the intelligent device built into the patch cord to light an LED at the far end of the cable to help the technician identify the correct cable.
- a user first plugs a ten-wire patch cord into the provisioning port of the PMM.
- the technician plugs the far end of the ten-wire patch cord into an Ethernet switch port or Ethernet router port, and finally moves the near end of the ten-wire patch cord from the provisioning port to the correct or desired patch panel port.
- the PMM will communicate via the 9th and 10th wire of the ten-wire patch cord to an intelligent device embedded in the ten-wire patch cord. From the ten-wire patch cord, the PMM will learn both the ten-wire patch cord's unique ID and the connection status (e.g., whether the far end of the ten-wire patch cord is coupled to a switch).
- the PMM can also instruct the intelligent device built into the ten-wire patch cord to light an LED at the far end of the cable to help a user identify the correct cable.
- FIG. 14 is a flowchart depicting functional steps of an example method for performing patching in an interconnect type architecture in a guided patching case.
- a PMM After initiating the guiding patching mode, a PMM will flash the LED above the provisioning port to indicate to the user where to insert the ten-wire patch cord, as shown at block 1402 .
- the user plugs the ten-wire patch cord into the provisioning port, and the PMM will establish communication with the intelligent device in the ten-wire patch cord at the far end (i.e., the end that is plugged into the PMM is the near end).
- the PMM will instruct the intelligent device within the cable to illuminate the far end LED to indicate that some action is required from the user (e.g., by flashing the LED), as shown at block 1404 .
- the PMM will send a simple network management protocol (SNMP) TRAP message to the NMS software indicating that a ten-wire patch cord was in the PMM provisioning port.
- SNMP simple network management
- CDP is used to obtain protocol addresses of neighboring devices and discover the platform of those devices. CDP can also be used to show information about the interfaces that a router uses.
- the LLDP is a vendor-neutral Layer 2 protocol that allows a network device to advertise the device's identity and capabilities on the local network. The LLDP protocol is fully explained within IEEE standard 802.1AB-2005, the contents of which are incorporated herein by reference.
- a CDP or LLDP packet will inform the PMM of the port address or location at which the ten-wire patch cord has been plugged, and the PMM can then determine if the I-Cord has been inserted into the correct port.
- other protocols could be used as well depending on the source of the data or type of patch cord being used, for example.
- the PMM will communicate to the intelligent device in the ten-wire patch cord and instruct the ten-wire patch cord to turn off the LED in the ten-wire patch cord, as shown at block 1416 .
- the PMM will also begin to flash an LED atop the provisioning port to draw the attention of the user and the user will then need to remove the ten-wire patch cord from the provisioning port on the PMM, as shown at block 1418 .
- the PMM will stop illuminating the LED above the provisioning port and will instruct the wing board to illuminate an LED above a patch panel port, as shown at block 1420 .
- the PMM detects whether the user has inserted the ten-wire patch cord into the correct port, as shown at block 1422 . If the user has inserted the cable into the wrong wing board port, the PMM will send an “unexpected ten-wire patch cord detected” message to the NMS. For as long as the ten-wire patch cord remains in the incorrect port, the port LED will continue to flash indicating an error and that further user action is required, as shown at block 1424 . When the user removes the cable from the wrong port, the PMM will instruct the wing board to turn off the LED indication on the wrong port.
- a time limit can be imposed on steps within the process, after which the process must be terminated or restarted. For example, a user may be given a specific period of time in which to perform the insertion of a plug of an I-Cord into a correct port (as detected at block 1422 ) after the I-Cord was removed from the provisioning port (as shown at block 1418 ).
- the above process will repeat until the user has correctly plugged in the ten-wire patch cord. Once the ten-wire patch cord is in the correct patch panel port, the wing board will communicate this information to the PMM and the PMM will send a message to the NMS indicating that the insertion has been completed successfully, as shown at block 1426 . The PMM will also indicate to the local user that the action has been completed successfully.
- the patch panel system of the present application provides almost-instant or real-time visibility to service disruptions (such as accidental disconnections) and accidental service activation (i.e., the unintentional creation of a connection) via real-time active monitoring of all patch field connections.
- service disruptions such as accidental disconnections
- accidental service activation i.e., the unintentional creation of a connection
- the time between an occurrence of such an event and visibility of that event at a management terminal may not exceed three seconds, for example.
- the patch panel system of the present application supports multiple configurations of cross-connect and interconnect topologies.
- cross-connect topology all patch panels have PMMs or PEMMs installed and nine-wire patch cords provide connectivity between the patch panels within the system.
- interconnect topology all patch panels have PMMs or PEMMs installed and ten-wire patch cords provide connectivity between patch panels and Ethernet Switches or Ethernet routers.
- the use of expansion ports on the PMMs supports the possible addition of future devices such as thermal, environmental, and power monitoring and management hardware. Additionally, the removable modular PMM enables field update capability because a user will be able to insert and remove the PMM from the system to upgrade the system without the need to change out a patch panel.
- a computer readable medium can include a readable memory device, such as a hard drive device, a CD-ROM, a DVD-ROM, or a computer diskette, having computer readable program code segments stored thereon.
- the computer readable medium can also include a communications or transmission medium, such as, a bus or a communication link, either optical, wired or wireless having program code segments carried thereon as digital or analog data signals.
- the form of the computer-readable medium of instructions can be provided in a variety of forms, and the present application applies equally regardless of the particular type of signal bearing media used to actually carry out the distribution.
- patch cords and patch panel ports according to other embodiments of the present application and that are designed for use in optical communication networks or in other electrical communication networks that do not employ RJ-45 plugs and jacks can be used as well.
- the use of the terms “nine-wire patch cord” and “ten-wire patch cord” in the present application apply to a traditional eight-wire RJ-45 connection.
- a “nine-wire patch cord” refers to any patch cord having one extra wire used for connectivity management purposes or other purposes as described herein.
- a “ten-wire patch cord” refers to any patch cord having two extra wires used for the purposes described herein.
